Campfire Cake in an Orange-- Cut the tops off oranges & scoop out the fruit. (Use the fruit for a healthy fruit salad.) Fill each orange just past halfway with prepared cake mix. Put the tops back on & wrap in foil. Set the oranges in the campfire coals for 20 minutes. The cake bakes right in the oranges and is very moist with a tinge of orange flavor... on the home grill?
